The biggest challenge to measure healthy ageing has been the plethora of ways to collect and analyse data. Given this challenge, it is necessary to make certain that measurement concepts are clearly defined and harmonised across surveys.
This collection of research articles systematically reviewed a vast number of surveys across several countries to identify best question items to use in surveys that measure healthy ageing. It also provides recommendations for items to include in standardized questionnaire and identified measurement areas in need of further research.
